Most conventional spacious solar photoelectric detection systems suffer from unexpected stray light. This paper demonstrates the effects on photoelectric detection system bring out by stray light. On this foundation, build up evaluation index of stray light system, to search the reasonable programme to eliminating stray light. A detailed telescope system geometry model was created, and scatter models were create for telescope and enclosure components. By the means of designing the structure of main baffle, baffle vane and the coating technology. In order to verify the prosperity of structure that designed, we utilizes software to analysis opto-mechanical model. we utilizes software to analysis opto-mechanical model. The simulations show that point source transmittance of the system is thus reduced by up to two orders of magnitude between 10-8 and 10-10. Meanwhile, the experiment obtains clean detection data which satisfies the system requirements. Stray light has been suppressed effectually, and so measurement precision was improved from detection graphics.
